My problem is that the numbers don't seem right. I took some simple
measurements of *my screen* displaying RGB(255,0,0), (0,255,0),
(0,0,255) and (255,255,255) and got the following numbers:
(45.7,23.15,0.37)
(48.9,90.8,8.09)
(24.54,10.02,122.8)
(127.97,132.8,136.5)
Seems alright. Note that these seem to be absolute, so you have to
divide all values by the white Y to get relative XYZ. The primaries
plotted on a xy or u'v' chromaticity diagram indicate a Rec709-ish
gamut, which seems sane (although the particular display should also be
capable of a gamut nearing AdobeRGB, depending on settings).
